Was Ist Das?
 

Hey. My inability to identify things in my tank astounds me :mrgreen:

But....what is this growing in the midst of my yellow polyps?

Thanks in advance!

Algae? I vote dictyota or sargassum.

the white on the tip is odd if its an algae.. could be a small coral.

btw, nice photo. Very clear and crisp. :)

It is a type of Sargassun Macro Algae... under the right conditions it can flourish. I had a piece start out about the same size as yours... it didn't do much for years. One day it just started growing and with in a month it had grown to the top of my 90g and covered most of the surface. It was fun for the first while watching it grow... then it became a pain... it grew so fast and the little bubble bits that will grow nearer to the top break off and clog everything.

Well, I thought it was probably algae, but....I was a bit confused by the white bit at the top. I thought it looked gorgonian-ish, but perhaps that was just wishful thinking :mrgreen:

BTW...does anyone with these yellow polyps feed them directly with mysis or anything? I've done so and they gobble it up like nuts. Just wondering if it's necessary.

Yes... I feed mine mysis they love the stuff.
